Materials Data on CuAsO3 by Materials Project

Abstract

CuAsO3 is Ilmenite structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Cu1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 2.07–2.53 Å. As5+ is bonded to six O2- atoms to form edge-sharing AsO6 octahedra. There are a spread of As–O bond distances ranging from 1.89–1.92 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Cu1+ and two equivalent As5+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Cu1+ and two equivalent As5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Cu1+ and two equivalent As5+ atoms.
